There is no question as to whether Paul Dirac was a great scientist. From his keen eye for mathematical beauties to his contributions as a pioneer in quantum mechanics, one can only argue that Dirac was anything but ordinary.
Dirac’s peak was between the years of 1925 and 1933. Despite being only one of many theoreticians who aided in the discovery of quantum mechanics, Dirac’s contribution was entirely special. He created a clear vision for quantum mechanics as it became a new branch of science and as Freeman Dyson puts it, “His great discoveries were like exquisitely carved marble statues falling out of the sky, one after another” (Farmelo 428).
During this time, Dirac held an 1851 Research Fellowship from the Royal Commission for the Exhibition of 1851 which allowed him to fund his research for the next three years. He also made close connections with theoretical physicist and quantum mechanics pioneer Werner Heisenberg starting in 1925, which would start a fifty-year friendship. At the young age of 24, Dirac completed his Ph.D. and produced the first thesis on quantum mechanics ever to be produced.
Unlike other quantum theoreticians, whose papers were hard on the eyes and imperfectly formed, Dirac’s book The Principles of Quantum Mechanics gave this new field a fine, polished look. He presented quantum mechanics as if it were a work of art—and to him it most surely was. In 1933, Dirac was awarded the Nobel Prize in Physics alongside Erwin Schrödinger for “the discovery of new productive forms of atomic theory” which arose from his years of research.
Despite being somewhat of an unknown face in a scientific community where intellectual giants such as Einstein and Darwin are most remembered, Dirac can be “counted as one of the greatest of all scientist” because the notions which were put forth by him are still being developed and continue to contribute to modern thinking (429). Today, scientists can smash together particles at high energies. They have created a huge particle accelerator at CERN which can recreate the conditions of the universe to within a millionth of a millionth of a second of the beginning of time. Dirac acted as a stepping stone for the scientific community by taking the position of a co-discoverer and by authoring the action-principle formulation of quantum mechanics.
